Abdominojugular test
The abdominojugular test, also known as abdominojugular reflux (AJR), is a physical examination test useful in diagnosing right ventricle dysfunction, particularly right ventricular failure.

| Purpose | Diagnosis of right ventricle dysfunction |
AJR is a test for measuring jugular venous pressure (JVP) through the distention of the internal jugular vein. A positive AJR test correlates with the pulmonary artery pressure and thus is a marker for right heart dysfunction, specifically right ventricular failure.
Reflux in this context means backup of the circulatory system and is not to be confused with reflex.
